of the rod e and link hf, pivoted to a dovetailed slide, m, which moves vertically up and down in corresponding guides a n, attached to or formed on the side of the cylinder A. By the up-and-down movement of the rodk and the connections, as described, the plunger G is moved up and down at the proper time-up to give room for the clay to enter the box E, and down to force and press the clay into the lnold. The links h and h', above mentioned, are each made in two pieces, joined together with nuts z' i, which are cut with right and left hand threads, whereby the links may be lengthened and shortened at will, so as to adj ust the length of the stroke of the plunger G. On the lower end of the rod k is formed a square slide, p, which is held and moves in a guide-box, p', and is provided with a pin, s, on its inner side. This pin projects into a cam-groove, t, made in a wheel, H, around its circumference, said wheel being firmly attached to the lower part of the central shaft B, and has beveled cogs fu on and around its lower edge. This wheel H thus receives motion directly from a main driving-shaft, and transmits it by means of the cam-groove t to the device for operating the plunger. I represents the moldwheel, provided with a series of inortises, a a', for the insertion of the briclmnolds. These mortises are countersunk around the upper edges, as shown at b', Fig. 2, which will admit of the insertion of new molds, or molds of different shapes. Fig. 7 represents one of these molds, which has a rectangular recess, and will form a rectangular brick. Around the upper edge of this mold R is a ilange, r', which, when the mold is inserted in the mold-wheel, will perfectly t in the countersink b. The recess in this construction of mold may be of an y suitable shape, such as diamond-shaped, polygonal, or other desired form. On the under side of the mold-wheel I are pins or rollers df, which are struck by an arm, J, attached to the upright center shaft B, for the purpose of revolving the mold-wheel. The mold-wheel I rests upon a center hub, j", and turns around a kin g-bolt, i', attached therein, and under the wheel is a cam-shaped ring, K, upon which the follower L is placed and moves, said follower having a curved and beveled groove in its under side to fit over the ring K. On the inner side of the follower L is a projecting' pin, p, near the lower end,-which works under a flange, M, arranged within the cam-shaped ring K, for the purpose of drawing the follower down as the mold-wheel revolves.

The operation of the machine is substantially as follows: The clay being passed through the arin g top or hopper into the cylinder, it is Worked by the cutters and wipers attached to the central revolving shaft, and fed into the boxes under the plun gers. Any stones or other hard substances in the clay will be worked into and lodge in the corners or recesses formed in the cylinder, so that they will not pass out with the clay. While in 4said corners or recesses the stones are out of the way, and can do no injury whatever to any part or parts of the machine.

When the corners or recesses are filled with stones or other such substances they may be easily cleaned out by means of a hoe or any other suitable means or devices.

The plunger is operated by the cam-groove in the wheel at the lower end of the revolving shaft by the pin s on the slide p operating in said groove, and by the joints or toggles communicating motion to the plunger.

The plunger in its downward motion forces and presses the clay into the mold, the follower having been drawn down by the flange M and pin p, and as the mold-wheel revolves the follower is forced upward, as is usual in this class of brick-machines, by sliding on the cam-rin g K, and thus expelling the brick.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l.. In combination with the upright cylinder and its shaft, the cast-metal top D, having a tlarin g or funnel-shaped rim, cross-arms d, and a central cap, b, all constructed substantially as and for the purposes herein set forth.

2. The large bevel-wheel H, provided with a cam-groove` t, on its periphery, and arranged under the cylinder, in combination with the main shaft and its knives, and with the levers and the follower, all substantial y as and for the purposes herein set forth.

3. In combination with the shaft B and the revolving brick-mold, the long arm J, arranged under the cylinc'e -bottom, and working in the slotted frame-work, substantially as and for the purposes herein set forth.

4. rIhe combination, with the follower and the wheel H t, ofthe rod e, lever f, links h It', rod la, and slide m, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 19th day of March, 1874.
